    <p>
    returns the value of the elliptic integral
    with parameter <tt>
        <b>ck</b>
      </tt> :</p>
    <p>
      <tt>
        <b>x</b>
      </tt> real and positive.
    When called with <tt>
        <b>x</b>
      </tt> a real vector <tt>
        <b>r</b>
      </tt> is evaluated for each
    entry of <tt>
        <b>x</b>
      </tt>.</p>
